Upon the occurrence
of an event of default and at any time thereafter, Payee, at its option and as often as it desires, may declare all liabilities, obligations, and indebtedness due Payee, including this Note, to be immediately due and payable without demand, notice,
or presentment, and may exercise any other remedy available to it under the Security Agreement or any other agreement given by Maker to Payee, and any other remedy available to it at law or in equity.

The remedies of Payee shall be cumulative and concurrent, and may be pursued singularly, successively or together, at the sole discretion
of Payee, and may be exercised as often as occasion therefore shall arise. No act of omission or commission of Payee, including specifically any failure to exercise any right, remedy or recourse or acceptance by the Payee of any payment hereunder in
an amount which is less than payment in full of all amounts due and payable at the time of such payment, shall be deemed to be a waiver or release of the same, such waiver or release to be effected only through a written document executed by Payee
and then only to the extent specifically recited therein. A waiver or release with reference to any one event shall not be construed as continuing, as a bar to, or as a waiver or release of any subsequent right, remedy or recourse as to a subsequent
event.

TIME IS OF THE ESSENCE OF THIS NOTE. Maker shall pay all costs incurred by the holder of this Note in enforcing or
collecting this Note and enforcing each agreement executed in connection with this Note (including any agreement under which real or personal property is pledged as security for this Note), including without limitation all attorneys fees,
costs, and expenses incurred in all matters of interpretation, enforcement, and collection, before, during, and after demand, suit, proceeding, trial, appeal, and post-judgment collection efforts as well as all costs and fees incurred by the holder
of this Note in connection with any bankruptcy, reorganization, or similar proceeding (including efforts to obtain relief from any stay) if Maker or any other person or entity liable for the indebtedness represented by this Note becomes involved in
any bankruptcy, reorganization, or similar proceeding.

The validity, construction, interpretation, and enforceability of this
Note are governed by the laws of the State of Florida, excluding its laws relating to the resolution of conflicts of laws of different jurisdictions. Maker further agrees that venue for each action, suit, or other legal proceeding arising under or
relating to this Note or any agreement securing or related to this Note shall be in a court of competent jurisdiction in Hillsborough County, Florida, and Maker hereby waives any right to sue or be sued in any other county in Florida or any other
state.



---

No provision of this instrument shall require the payment or permit the collection of
interest in excess of the maximum permitted by law. If any excess interest is herein provided for, paid by Maker or received by Payee, or shall be adjudicated to be so, the provisions of this paragraph shall govern, and neither Maker nor its
successors or assigns shall be obligated to pay the amount of such interest to the extent that it is in excess of the amount permitted by law, and any such amounts so paid, at the option of the Payee, shall either be applied against the Principal
Amount of this Note due at maturity, or rebated to Maker within thirty (30) days after final repayment of this Note.

Maker and any other person liable for the payment hereof respectively, hereby (a) expressly waives any valuation and appraisal,
presentment, demand for payment, notice of dishonor, protest, notice of nonpayment or protest, all other forms of notice whatsoever, and diligence in collection; (b) consents that Payee may, from time to time and without notice to any of them
or demand, (i) extend, rearrange, renew or postpone any or all payments, (ii) release, exchange, add to or substitute all or any part of the collateral for this Note, and/or (iii) release Maker (or any co-maker) or any other person
liable for payment hereof, without in any way modifying, altering, releasing, affecting or limiting their respective liability or the lien of any security instrument; and (c) agrees that Payee, in order to enforce payment of this Note against
any of them, shall not be required first to institute any suit or to exhaust any of its remedies against Maker (or any co-maker) or against any other person liable for payment hereof or to attempt to realize on any collateral for this Note. Maker
agrees that its obligations under this Note are independent of the obligation of any other maker, guarantor or other person or entity that now or later is obligated to pay this Note. Maker also agrees that Payee may release any security for or any
other obligor of this Note or waive, extend, alter, amend, or modify this Note or otherwise take any action that varies the risk of Maker without releasing or discharging Maker from Makers obligation to repay this Note.

The term Maker as used herein, in every instance shall include the maker and its successors and permitted assigns, and shall
denote the singular and/or plural, the masculine and/or feminine, and natural and/or artificial persons whenever and wherever the context so requires or admits.

Whenever Payee is referred to in this Note, such reference shall be deemed to include the successors and assigns of Payee, including, without limitation, any subsequent assignee or holder of
this Note, and all covenants, provisions, and all agreements by or on behalf of Maker and any endorsers, guarantors, and sureties hereof which are contained herein shall inure to the benefit of the successors and assigns of Payee.

This Note may not be modified or terminated orally, but only by agreement or discharge in writing and signed by Payee and Maker. Any
forbearance of Payee in exercising any right or remedy hereunder, under the Mortgage or under any other loan document relating to this transaction shall not be a waiver of or preclude the exercise of any right or remedy. Acceptance by Payee of
payment of any sum payable hereunder after the due date of such payment shall not be a waiver of Payees right to either require prompt payment when due of all other sums payable hereunder or to declare a default for the failure to make prompt
payment in the future.



---

For and in consideration of the funding or renewal of the indebtedness evidenced hereby,
Maker further agrees to cooperate with Payee and to re-execute any and all documentation relating to the loan evidenced by this Note which is deemed necessary or desirable in Payees discretion, in order to correct or adjust any clerical errors
or omissions contained in any document executed in connection with the loan evidenced by this Note.

Each required notice,
consent, or approval, if any, under this Note will be valid only if it is given in writing (or sent by telex, telegram, or telecopy and promptly confirmed in writing) and addressed by the sender to the recipients address that is listed in this
Note or to such other addresses as either party may designate by written notice to the other party. A validly given notice, consent, or approval will be effective (i) on receipt of hand delivery to the recipient, (ii) seven (7) days
after having been deposited in the United States mail, certified or registered, return receipt requested, sufficient postage affixed or prepaid, or (iii) one (1) business day after it is deposited with an expedited, overnight courier
service (such as by way of example but not limitation, U.S. Express Mail, Federal Express or Airborne). These notice provisions apply only if a notice is required by this Note. They do not apply if no notice is required by this Note. This Note is
not assignable by Maker.

WAIVER OF JURY TRIAL.MAKER AND PAYEE HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE ANY AND ALL RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION (INCLUDING, BUT NOT LIMITED TO, ANY CLAIMS, CROSSCLAIMS OR THIRD-PARTY CLAIMS) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE, THE PURCHASE AGREEMENT, THE
OTHER TRANSACTION DOCUMENTS, OR ANY OTHER LOAN DOCUMENT EVIDENCING, SECURING, OR RELATING TO THE INDEBTEDNESS EVIDENCED BY THIS NOTE OR TO THE DEALINGS OR RELATIONSHIP BETWEEN OR AMONG THE PARTIES HERETO. NEITHER MAKER NOR PAYEE WILL SEEK TO
CONSOLIDATE ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL HAS NOT OR CAN NOT BE WAIVED. THE PROVISIONS OF THIS SECTION HAVE BEEN FULLY NEGOTIATED BY THE PARTIES HERETO, AND THESE PROVISIONS SHALL
BE SUBJECT TO NO EXCEPTION. MAKER HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF PAYEE OR PAYEES COUNSEL HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT PAYEE WOULD NOT, IN THE EVENT OF SUCH LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT
